...luckily, it's not so much a bug, as it is an odd
implementation ;-) The default draw style of cube is GL_QUADS, and
you can get this either by [draw default< or [draw Quads<
[draw fill< actually switches it to GL_POLYGON...so this may point
out that we need a different order of vertices/faces to create the
expected shading...
